SPECIFICATION forming part of Letters Patent No. 783,085, dated February 21, 1905. Application filefl November 21, 1903. Serial No. 182,109.

To (LIZ- '1071/0711, it4 '1m/.y concer/1,.'

Be itlmown that l, JAM ns F. S'invicxs, a citizen of the United States, residing at Port Chester, in the county ol" Westchester and State of New York, have invented anew and useful Machine to be Used forthe M ixingand lx'neadingoBread, ofwhich the tollowingisaspecilication.

My invention relates to an im1:n'ovement in bread mixers and lcneaders; and the object of my improvement is efiicicney in operatirm with reference both to the mixing and lineading operations.

ln `the accompanyingdrawings, Figure 1 is a sectional plan of a. beater and vessel, the plane of section for the beater being on the line :zf of Fig. 2. Fig. 2 is an enlarged sectional elevation of the machine on the line ,//y/ of Fig. 1 with parts broken away and the beater rotated one-quarter of a revolution from the position shown in Fig. 1.

The machine herein shown is made in aecordance with some of the features in each of the following patents: to Munson, No.7298i, June 2, 19Go; to Garrigus and \Varner, No. 736,956, August 25, 1903, and to Stevens, reissue No. 12,167, November 3, 12h13.

A designates the vessel, haring underneath the bottom 3 the clamp-receiving' soclqeta and feet 5, by means of which socket and clamp (not shown) the vessel may be lirmly secured to a table, as in the said Munson patent. At the top of the vessel is the detachable crossw piece or frame 6, having' the bearing?, within which bearing the hub 8 of the crank 9 is journaled, the said hub being axially perforated with an angular hole to receive the angular shank 10V of the beater-shaft 11. lhe upper end of the said shank is provided with a narrow neck 12'for the engagement of the latch 13, asini/he said Garrigus and Warner patent, although as herein shown the cranlvhub is detaell Ableifrem the bearing and the shaft 'igidlyis'eeured thereon the llange lit at a pointjufst below the angular shank.

The beateiris composed of a bent rod, with the lower member 15 approxi mately approaching the bottom 3 of the vessel A and extend- I ing over substantially halt' the diameter therel com bination oi a vessel with a rod-like beater of in a position parallel to the said bottom.

i l i l l i i i l l i l l l i i l l i One end ot' the said lower member merges into an outwardly, upwardly, and inwardly extended bent portion 1,6, which has sometimes been called the connecting member. This bent portion 16 at its greatest diametrical p rejection falls considerably short of reaching the side ot' the vessel, thereby leaving an ample working space for the dough to escape and pass by or roll around the saidbent portion ot' the beater. The upper end 17 of the ben t portion practically forms the upper part ot' the beater proper, butas in the Stevens reissue before named there is a short bend 18, extending laterally a short distance at a point between the said upper end 17 and the axial portion olj the beater-shaft 11 adjacent to where the said shaft is supported in its bearings. '1`he general form of the beater, consistingofl bent rod with a lower member and an outwardly and upwardly and inwardly bent or connecting member, all mounted to rotate on a vertical axis in the cross-bar ot' a vessel and extend downwardly into the vessel, is old and of itself is not'herein claimed. By my improvement the lower mem ber ap proxim atcly approaches the bottom ol the vessel and stands in a parallel position thereto, while the connecting or bent portion which extends upwardly therefrom is remote from the sides ot' the vessel. The lower merf her thus related to the vessel is a good device Afor mixing dough, but such a relation is not an effective one for the kneading operation. Provision, however, is made for an effective kneador by keeping the connecting or bent portion 1G remote from the sides ot' the vessel, thereby leaving an ample working space be? tween the said portion and side of the vessel for the dough to escape from the beater or pass by it du ring the lmeading operation.

A machine that is both an eiiicient mixer and eliieient kneader is produced in one machine instead of producing one machine that is especially ei'licient for mixing' and another machine that is especially eliicient for l( nead i ng'.

l claim as my invention- A bread mixer and kneader comprising the n'iounted to rotate on a Vertical axis within BEST AVAILABLE COD the said vessel, the said beater having a consaid bent portion to near the side of the vessel necting portion projectingr diametrically relat1vely to, but less than the Working diameter of the vessel, for forming an ample kneading'- space between the said bent portion and side of the vessel for the dough to escape during' the kneeling operation, and having a lowei member extendingfrom the lower end of tbe and in proximity to the said bottom for use I0 as a mixing member.
